Why do people say your cats have died when your trousers are short at the hem?

Well, honey, people say your cats have died when your trousers are short at the hem because it's an old-fashioned way of pointing out that your pants are too short. It's just a quirky way of saying your clothing doesn't fit properly and looks a bit off. So, next time someone mentions your cats kicking the bucket, maybe it's time to invest in some longer pants.
